Public Schools near me in SF Bay area are more focused on political ideology than improving kids ability to attain Literary, Math, and Science education. There is a push for Equity over Achievement, by bringing the top performers down to raise the bottom. However the top performers have left for private school, and Public institutions declined. It's a downward spiral. There's hope it'll change either through full dissolution of the public institution (voucher programs) or through the dissolution of such "equity at all cost" political ideology.
This situation, where it is true at all, is a vanishingly small minority when accounting for these across-the-board downward shifts in national data. Oppose it locally if you wish but extrapolating your local situation to a national level doesn't hold up.
Whereas at least 75% of elementary students nationwide are learning cueing, so starting there makes more sense.
San Francisco Unified School District implemented math sequencing changes that failed. District Leadership claimed they worked. Those changes were then cited by the authors of the latest California Math Framework.
Because California is a big state (and with some popular state universities), the California Math Framework will influence curricula and teaching methods far beyond California.
This is specious. Can you show me direct evidence that these policies have been adopted nationwide to the broad degree necessary to explain the data as presented in the original post?

No, not 'to the broad degree necessary to explain the data'. But no one in this thread is claiming that these policies alone explain the data.
You say it's a local thing only. I explain how local things expand. You say it's a hypothetical. I say no these things have expanded already. You say that doesn't fully explain the data.
If you will dismiss any hypothesis that doesn't fully explain the data, you will never receive a satisfying answer.
You've been downvoted, probably due to the opinions/hopes in the last sentence. Many people strongly believe that government-funded education must be government-run.
I won't comment on those opinions, but what you've written earlier in the paragraph is broadly correct, at least in San Francisco.
However, private schools are not a panacea. Most of them still group kids by age and do not tailor content to each kid's level, or even do single-subject acceleration.
